Throw it up on some jack stands and check it out, within reason Should be able to verify if the diff has engaged, or not. All four should have been pulling within like a 1/4 turn of the rear wheels.

 

This is how my stealer said they test them...

 

When I check the 4 wheel drive on Gators at work I will do this. Put the machine up on jack stands and check with no load. Then I will strap the ass end to a poll and spin the tires on the smooth floor. Then I will do the same outside on the rough cement, burn some rubber and listen for the popping noise.

 

Ok, was hoping for a safer way, but will try that.

Thx

 

Ok, then jack stands it is.

Thx boys.

 

Remember RPM must be below 3000 for AWD to engage!!!

 

Yes. I was stopped.

 

the front diff is def the one thing i miss about my rhino. when you locked it in you knew for a fact you was in 4 wheel drive. none of this slipping tires crap for it to lock in. i'd love to fab in a rhino diff to the front of my rzr. i've had my 4 wheel drive not kick in now a couple times on some nasty hill climbs.

 

Grant, if you verify that the demand drive is not working I recommend you flush out the case with about a half quart of mineral spirits (Varsol tm) then add a quarter quart of demand drive fluid, ride it for a few minutes, drain and fill with DD fluid to specs. This may solve the issue being that the electrical components test fine (doesn't mean that the armature plate is not warped though). Might avoid a tear down and easy enough to do. If this doesn't work you'll have to get inside the unit.

 

Thats good to know.

 

There is lots of us that miss 4WD/LOCK. CHALENGE TO OUR VENDORS: come up with an AWD override switch so the driver has control to keep them pulling... I would buy one now, the fan overide works. the AWD is electric so I am sure it could be done.

 

As for an override switch... might not be a good idea to be able to kick in the awd at wot by mistake...

jmo

 

Maybe forward your post to whoever makes the fan override?

 

Update:

Took my rzr over to hav19's shop to put up on the lift rack.

The awd was working.

Thx John

 

Figures.... :rofl3:

Can't be done with the Hilliard drive. If the switch is on it allows the front axles to "lock" to the ring gear providing power to the front wheels ONLY when the rear wheels are turning faster than the front. The switch (when off) will basically allow you to keep the front drive from engaging but the actual engagement inside the drive unit is a mechanical system based upon differential speeds between front and rear wheels.

 

Well, it's better than finding out something was wrong, right?

Especially after I over torqued a bolt on the sea doo today and cracked the crank case. $600 mistake.

F my life!
